Very interesting to say the least, when I first started reading the article, I thought "Oh, they are just using an EMCCD!", but then it said they were using a CMOS sensor. Makes me wonder if they are using the new sCMOS sensor, which has very, very low noise, and then just ramping up the gain (ISO). The capability, based on the example image, seems on par with current EMCCD technology.
It'd be interesting to see this compared to something like a AF100 / C100 / 5DIII with a fast lens. Comparing to a consumer handy cam is a very low standard for low light situations.
